RSSI-BASED INDOOR POSITIONING IN THE PRESENCE OF DYNAMIC TRANSMISSION POWER CONTROL ACCESS POINTS

摘要

A position fix for a mobile device is determined using RSSI values for wireless signals received from access points (APs), at least one of which has dynamic transmission power control. The transmission power data for the APs is received from an entity separate from the APs, e.g. a central entity or a positioning assistance server. The RSSI values for wireless signals received from the APS are acquired. Using transmission power data and the RSSI values, the position fix for the mobile platform is determined.
